The hybrid transport model AMPT is widely used in simulating relativistic heavy-ion collisions. The string melting version, in particular, is known for describing the collective motion of the final state hadrons [1]}. AMPT consists of four subroutines which simulate different stages of the collisions in sequence: HIJING for the initial parton condition [2]}, ZPC for the partonic evolution [3]}, a simple quark coalescence for the hadronization process and ART for the hadronic rescatterings and interactions. In this work, the parameters of Lund string fragmentation and the cross section of parton scattering are set to reproduce the hadron spectrum and anisotropic flow at RHIC and LHC energies [4]}, [5]}. To mimic the CMW-induced electric quadrupole moment, the approach proposed in Refs. [6]}, [7]} is performed, which interchanges the \(y\)  component of the position coordinate for some in-plane light quarks carrying positive (negative) charges with those out-plane ones carrying negative (positive) charges. The strength of the quadrupole moment is determined by the number of quarks being interchanged. Previous studies suggest that switching \(\approx \) 3% of total quarks can generate a comparable slope with the experimental result in semi-central collisions [7]}, [9]}.
